can almost eat them like an apple. A classic long-day onion for northern gardens, it is a rewarding, impressive crop for anyone who loves a gentle, sweet onion. Who it's for Perfect for northern gardeners and sweet-onion lovers. Walla Walla is a long-day onion, so it bulbs best in the longer summer days of the north, and its exceptional mildness makes it a favorite for fresh eating. Growing your own giant sweet onions is a genuine treat. How & when to plant Start Walla Walla seeds indoors 8 to 10 weeks before your last frost, or sow in late summer to overwinter in mild-winter areas. Plant the seeds about a quarter to half an inch deep; they germinate in about 7 to 10 days. Thin or transplant seedlings to about 3 to 4 inches apart in full sun, in rich, loose soil. Growing & care Sweet onions need steady moisture and a clean, weed-free bed to size up well. Water consistently as the bulbs swell, feed them early, and taper off watering as the tops begin to fall near harvest. As a long-day type, Walla Walla needs the long summer days of northern latitudes to bulb properly. Harvest Harvest when most of the tops have bent over and started to dry, usually around 110 to 125 days. Lift the big bulbs gently and cure them in a warm, airy, shaded place. Sweet onions like Walla Walla do not store long, so enjoy them fresh over the weeks after harvest. Benefits & uses Walla Walla onions are all about sweet, mild flavor. Slice them raw into salads, sandwiches, and burgers, where their gentleness shines, or grill, roast, and caramelize them until meltingly sweet. They make wonderful onion rings and a superb base for savory dishes.
